Supplying and installing dual-pitched roof patent glazing for new two-storey office
When Powys-based soft drinks supplier Radnor Hills planned to extend its office facilities, the company was keen to follow its sustainability ethos, including the use of natural daylight.
“Our builder recommended Howells Patent Glazing for the supply and fit of the atrium, and we were happy to go with their advice,” said building manager Wayne Priday.
“Howells have been extremely good to deal with. They guided us on what we needed and recommended which glass and framework would best meet our requirements.”
Howells supplied an area of dual-pitched roof patent glazing built using its HG57 aluminium bar. The rooflight measures 9.29m long by 2.84m on each slope.
The aluminium bar is polyester powder coated in Matt Anthracite Grey (RAL7016) on the exterior face and Matt Cream (RAL9001) internally. This finish is extremely durable and protects the metal from the elements – an important factor in open country.
The aluminium frame is glazed with 28mm double glazed units, comprising a 6mm toughened SunGuard SuperNeutral (SN) 70/35 glass outer pane, and a 6mm clear toughened inner, with a 16mm argon filled cavity with warm edge spacer.
The outer pane is a neutral blue glass which offers excellent solar protection while reducing the need for artificial light. Ideal for large, glazed windows SN 70/35 also provides outstanding thermal insulation. This is an essential consideration for the two-storey building – with soaring energy costs, energy efficiency was a key criterion of the specification. The rooflight achieves a 1.0 W/m2K U-value .
Tracey Jackson, business development manager for Howells Patent Glazing, said: “It is always a pleasure to support businesses who understand and appreciate the importance of natural day light for completing tasks and creating healthier workspaces. It is proven that the performance and productivity of workers can increase with the quality of light, as such our dual-pitched roof patent glazing will improve mood, boost morale, and reduce fatigue and eye strain (Robbins, 1986) amongst the office staff at Radnor Hills.”
